APPARATUS FOR EXTRAGTING AND DISTRIBUTING NICOTIN.

Specification of Letters Patent.

Patented Aug. 29, 1911.

Application filed April 13, 1911. Serial No. 620,809.

To all whom it may concern:

Be it known that I, KARL BoLL, a citizen of the United States, residingat Fort Madison, in the county of Lee and State of Iowa,

have invented certain new and useful Improvements in Apparatus forExtracting and Distributing Nicotin; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to an improved apparatus for extracting nicotinfrom tobacco leaf stems and distributing the nicotin within a limitedradius.

One object of the invention is to provide an apparatus of this characterin which tobacco stems are placed and subjected to an application ofsteam under suitable pressure whereby the nicotin will be extracted orliberated and a portion of the same will be vaporized and dischargedfrom the receptacle with the steam and will thus be distributed within alimited radius.

Another object is to provide an apparatus of the character describedwhich will be simple, strong, durable and inexpensive in construction,eflicient in operation and well adapted to the purpose for which it isdesigned.

lVith these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claim.

In the accompanying drawings: Figure 1 is a perspective view of theinvention, parts of the same being broken away and in section; Fig. 2 isa central vertical sectional view thereof; Fig. 3 is a horizontalsectional view of the same; Fig. 4 is a perspective view of the cap anddischarge tubes of the apparatus showing the same separated; Fig. 5 is asimilar view of the false screen bottom of the receptacle.

My improved extracting and distributing device comprises a hollowcylindrical body portion or receptacle 1 having a main bot-- tom 2 onits lower end and a removable conically shaped cap 3 on its upper end.In the center of the cap is arranged a discharge opening 4 with which isconnected a short discharge pipe 5. To the upper end of the dischargepipe 5 are connected the inner ends of distributing pipes 6, which arebranched or project in opposite directions as shown.

In the receptacle 1 and resting on the main bottom 2 is a false bottom7, said bottom comprising an annular band or ring 8 of suitable widthand having formed therein an annular series of steam passages 9. On theupper edge of the ring is secured a wire netting screen 10, said screenforming the false bottom of the receptacle upon which will rest thestems placed in the tank, said stems being thus supported above the mainbottom of the receptacle. Thefalse bottom 7 is of less diameter than thereceptacle and between the inner side of the receptacle and theapertured ring 8 of the false bottom is formed an annular steam space11.

In one side of the receptacle is arranged a tube 12 the inner end ofwhich communicates with the steam space 11 while to the outer end isadapted to be connected a steam supply pipe whereby steam under thedesired pressure is admitted to the steam space 11 and from thencepasses through the apertures in the ring 8 to the space below the falsebottom 7 From said space the steam passes up through the screen and isevenly distributed through the tobacco stems with which the receptacleis filled. The steam in thus passing up through the stems extracts orliberates the nicotin therefrom, whereupon the greater part of thenicotin thus liberated commingles with the steam and is dischargedtherewith through the discharge pipes. lVhen in the commingled state itdisseminates in every direction and the nicotin precipitates and settleson all surfaces within a certain distance from the apparatus. Theremainder of the nicotin so extracted from the stems which is notdischarged from the receptacle settles with the condensed steam into thebottom of the receptacle below the false perforated bottom in the formof a fluid extract, and may be removed in any suitable manner andutilized as an insecticide which may be sprayed or otherwise applied tothe plants.

From the foregoing description taken in connection with the accompanyingdrawings the construction and operation of the invention will be readilyunderstood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claim.

Having thus described my invention what I claim is:

An apparatus for extracting nicotin from tobacco leaf stems anddischarging said nicotin by means of steam, said apparatus comprising areceptacle adapted to contain said stems, a cap engaged with the upperend of said receptacle, discharge pipes arranged on said cap, a falsebottom arranged 011 the main bottom of the receptacle, said false bottomcomprising an apertured ring of less diameter than and spaced from thesides of the receptacle, a wire netting screen arranged on said ring,and a steam inlet tube arranged in one side of the lower end of thereceptacle whereby steam is discharged into the latter and passesthrough said apertured ring, and up through the screen forming saidfalse bottom and through the stems in said receptacle whereby thenicotin will be extracted from the latter and discharged with the steamthrough the discharge pipes on said cap.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
